Ben Carson officially dropped out of the presidential race Friday. Carson said this week that he saw no 'path forward' for his presidential campaign and did not participate in Thursday night's Republican debate, but he had not formally dropped out. He said Friday that he realized he didn't have the support or votes to win the contest. 'I did the math,' Carson said of his decision to drop out. 'I looked at the delegate counts, I looked at the states, I looked at the requirements and I realized it simply wasn’t going to happen and if that’s the case, I didn’t want to interfere with the process.' Carson said he will be involved in efforts to get evangelical Christians to vote. “I will still continue to be heavily involved in trying to save our nation. We have to save it,' he said.
